Let cure for a week or more and finish with Johnson's paste wax. Week later with a coat of Renaissance wax.


Please make a sample board with your finish on one side and and the same finish on the opposite side but leave out the mineral spirits. Then cut the board in half, wait a day and look at the difference in penetration. Solvents improving penetration is a myth. And they create issues in other ways.


So you recommend not cutting tung oil with mineral spirits?

That is correct. Solvents seem to make finishes thinner, but the basic molecules are still the same size and the solvents simply run away from the finish... basically the wood acts like a filter. The reason for waiting a day after cutting the sample board is the wood is often still wet with the solvent and the finish looks to have penetrated more deeply. It doesn't.
